An example Workspace for a small company, with a Claude chat on pricing just saved to the decision’s notebook. ## How do founders use Kortex? Founders and small business owners use Kortex, a Chrome extension for Gemini Notebook (formerly NotebookLM), to keep market research, competitor pages, customer conversations and AI brainstorms in a notebook per question they’re working on. They turn those notebooks into briefs, investor and board prep, and audio they can listen to between meetings. ### Workflows on this page 1. [Give each big decision a notebook](#decisions) 2.

Kortex gives it a place to live. - **The reasoning behind last quarter’s decision lives in your head and an AI chat.** Send the ChatGPT, Claude or Gemini chat where you worked it out to a notebook for that decision. - **Market research is forty tabs you’ll never reopen.** Highlight and send what matters as you read. Crawl a competitor’s site into a notebook in one go. - **Customer calls get recorded and never revisited.** Add transcripts to a Customers notebook and ask for the themes, each cited to the call it came from. - **Board and investor prep starts from scratch every quarter.** Duplicate last quarter’s prep notebook, update the sources, and generate a briefing doc or slide deck from it. - **There’s no time to read.** Generate an Audio Overview of a notebook and listen to it in your podcast app. ## Four routines for running the company Four routines for the decisions you make every week. ### Give each big decision a notebook The options, the evidence and your reasoning, kept together. 1. Create a notebook for the decision, like Pricing for teams, in a Company collection. 2. Send the AI chats where you explored the options, with your prompts and the replies labelled. 3. Highlight and send the articles and competitor pages you weighed. 4. Ask the notebook to lay out the options and the evidence for each, and save the answer as a note. ### Find what customers keep saying Recurring themes, each with the call or thread behind it. 1. Add call transcripts and survey exports to a Customers notebook. 2. Send Reddit posts and X threads where people discuss the problem you solve. 3. Ask for the recurring themes with quotes, each cited to its source. 4. Turn the gaps into interview questions with the [market research questions prompt](/prompts/market-research-questions). ### Prepare the board or investor update A first draft of the update, built from last quarter’s. 1. Duplicate last quarter’s prep notebook in one click and update its sources. 2. Generate a briefing doc and a slide deck from the notebook, then check every number. 3. Generate both at once and edit them before you download. 4. Find every past update in All Artifacts, filtered by notebook. All Artifacts ![The All Artifacts view in the Kortex Workspace, listing a study guide, notes, flashcards and a quiz, each with the notebook it came from, such as Neuroscience and Cryptography.](/media/tour/tour-artifacts-1200.webp) The real All Artifacts view in the Kortex Workspace. ### Get a weekly market brief The market as audio on Monday morning. 1. Crawl each competitor’s site into a Market notebook with the web crawler. 2. With Kortex MCP, say once: “Every Monday at 8, ask my Market notebook what changed and make it an Audio Overview.” 3. Listen to it in your podcast app on the way in. ## What reviewers say about these features Quoted word for word and linked to where they were posted.

I can make all sorts of enquiries in Gemini and then Kortex consolidates them into a single notebook where I can review what I have found and make sense of it all.

[Ask us](#contact). ### What is Kortex good for in a one-person business? Collecting the research you do anyway. Send the chats, pages and videos you read to one notebook per client or project, then search, tag and export from there. ### Can I keep company and personal research apart? Yes. Use a collection for each, or keep them in different Google accounts and switch between them in one click. ### Can it make my investor deck? Gemini Notebook can generate a slide deck from your sources, and Kortex lets you find and download it, or preview and edit it first. Treat it as a first draft: the numbers and claims need your check. ### Is my company data private? Kortex doesn’t keep your chats or the contents of your sources; imports go to Gemini Notebook in your own Google account, and Kortex never sees your Google password. See [is Gemini Notebook safe and private?](/blog/gemini-notebook-privacy) ### Can my team use it? Each person installs Kortex for their own account, and notebooks are shared from Gemini Notebook. ## Start with the decision in front of you. Add Kortex to Chrome and send the chat where you’re thinking it through to a notebook.
